Refurbishment & building in Harrow.

We know
Harrow.

Harrow is classic outer-London suburbia, built largely on interwar semis and detached houses with wide plots and good scope to extend.

The larger gardens and side accesses make Harrow one of the easier areas for ground-floor extensions and garage conversions, and much of it falls outside the tighter inner-London conservation rules.

In the HA postcodes we are most often asked for rear and side extensions, loft conversions, garage conversions and full refurbishments.

Metro-land semis
and bigger plots.

Most of Harrow was built in the 1920s and 1930s as the Metropolitan line pushed out from London: semi-detached and detached houses with hipped roofs, front bays and gardens front and back, in Harrow itself, Wealdstone, Kenton and Headstone. On and around Harrow on the Hill the houses are older and the streets more protected.

We work across Harrow, Wealdstone, Kenton, Headstone and North Harrow. Most houses are interwar, but each street has its own mix of original and extended houses, so we look at what neighbours have already built when advising what is likely to be approved.

Two-storey side and rear extensions

Wider plots mean Harrow houses can often extend sideways as well as back, adding a garage conversion, a utility or a fourth bedroom over the side.

Hip-to-gable lofts

Converting the hipped roof to a gable and adding a rear dormer is the usual Harrow loft. It needs structural design and building control, and often fits within permitted development.

Roofs and rainwater

Original 1930s roofs, fascias and soffits are reaching the end of their life on many streets, and are worth renewing before any loft or extension ties into them.

The projects
we quote most.

Harrow enquiries are mostly for extensions, loft conversions, new kitchens and bathrooms, roofing and fascias and soffits, and boiler replacement.

Using the
whole plot.

Harrow gardens are often long enough for a garden room or home office, and many houses have a garage that is used for storage rather than cars. Converting the garage into a room, or building an outbuilding at the end of the garden, can be a cheaper way to add space than an extension. Outbuildings within the size and height limits are often permitted development, but they still need sensible foundations, insulation and a safe electrical supply.

Bigger kitchens,
better layouts.

Many Harrow semis still have a small kitchen at the back with a separate dining room. Knocking through and extending at the rear creates the open kitchen most families want. We manage the structural work, drainage and the new kitchen as one project, with one contact from start to finish.

From first call
to finished in Harrow.

1. Measure up

   We visit, measure the house and plot, and talk through what the council is likely to allow.

2. Design and approvals

   Where needed we line up drawings, structural calculations and building control before starting.

3. Fixed written quote

   A written price for the whole project, agreed before any work.

4. Managed build

   One contact runs every trade from groundworks to decorating.
